Currently all ExpertVoice orders fall within a personal use only prevision and we collect sales tax on all orders. As such we do not directly support tax exempt orders as these orders are not intended to be used by an organization. In the event that you wish to request a sales tax refund you will need to provide us a copy of your tax-exempt certification and photo of the credit card showing the tax exempt status for each order you submit. Please send the required documents to Support@ExpertVoice.com with the subject line "Tax Refund request for order #[insert order number]". We will submit the request to our finance team and after that request has been completed any documents associated with that request will be shredded for your organization's safety.
